This file consists of conversions taken from the Dark Side Sourcebook for the d20 Star Wars Roleplaying Game.

- Brief Supplement Overview -

The long-anticipated Dark Side Sourcebook gives players and GMs a good grasp on the ways of the Dark Side of the Force, from the ancient Sith to modern Dark Side adepts, and everything in-between. Although it presents things that relate directly to game mechanics, it also includes a ton of background material which is, in my humble opinion, far more important than gizmos and gadgets. Anyone wanting to run or portray a Dark Side character needs to at least skim through this book. Investing an hour or two in order to read portions in depth is time well-spent.

The supplement has good lay-out and organization, with the interior art being a mixture of drawings/paintings and photographs from the movies. Everything is explained well, and most people won't have any trouble understanding the concepts that the book delves into. It is a hard-bound book with a glossy cover, runs a total of 159 pages, and seems to be constructed of high-quality materials. The cover price lists at $29.95, though I got mine somewhat cheaper on Amazon.com.

A word of warning: this supplement is powerful stuff. It is possible to integrate too much of a bad thing into any Star Wars game. Use with caution, and only under adult supervision. Just about everything in the Dark Side Sourcebook grants Dark Side Points. While D6 Star Wars is fairly adamant about players portraying good (or, at the most, shady) characters, d20 is a bit more apathetic. It takes a few more Dark Side Points in d20 (twice as many on average) for a character to be taken over by the Dark Side, and players whose characters turn to the Dark Side in d20 aren't forced to roll up new personas. To use all of the presented material might require GMs to throw some of the D6 rules concerning Dark Side Points out the window.

Should you buy it? If you want to get the most out of this conversion, then you should definitely pick this book up. The vast majority of the material presented doesn't require game mechanics, and it can only enhance any games you want to run in which the Dark Side of the Force has any bearing. It's my opinion that the Dark Side Sourcebook is a good addition to any Star Wars gaming library.

- Force Powers -

Control Powers

Channel Rage (Adapted from "Rage", DSS, page 18)
Control Difficulty: Easy.This power may be kept up.Warning: A character who uses this power automatically receives a Dark Side Point.
Effect: This power, when used, channels the character's anger and rage into a berserk fury, which increases his prowess in battle. Game effects include a temporary +2D bonus to Strength, and a -1D penalty to all defensive skill rolls. Raging characters are unable to perform any action or Force power that requires patience and/or concentration. When use of Channel Rage ends, the user loses 2 pips from his Strength die code for every round the power was kept up (reducing his Strength die code to a minimum of 1D).

Control and Sense Powers

Sith Sorcery (Adapted from DSS, page 18)
Control Difficulty: Difficult.Sense Difficulty: Moderate.Required Powers: Enhance Attribute, Feed on Dark Side, Life Detection, Life Sense, Sense Force.Warning: A character who uses this power automatically receives a Dark Side Point.
Effect: Sith Sorcery is used to channel the spirits of dead Sith lords into a character's body, augmenting his own natural abilities at the risk of possession. If successful, this power grants bonuses to attacks, resistance rolls, Strength (to resist damage only), and any use of Dark Side Force powers (ie, any powers that give Dark Side Points when used). The extent of the bonus and the power's duration are determined by the amount the Jedi's Control roll exceeds the difficulty. The duration can be increased by spending character points  for each character point spent, the duration is increased by one round. These points can be spent at any time before the power fades.

Special: Whenever Sith Sorcery is used, in addition to receiving a Dark Side Point, the character opens himself up to possession by Sith spirits. He must immediately succeed in a Moderate Willpower skill check, with the difficulty increased randomly by the amount of the bonus received. For example, a Dark Jedi beats his Control roll difficulty by 8 points, gaining a +1D bonus. When the power fades, he must make a Willpower roll with a difficulty of Moderate +1D. If the skill roll succeeds, there are no complications. If it fails, however, the character is possessed by a Dark Side spirit (see rules on Dark Spirits).

Sith Sword Combat (Adapted from Sith Sword Defense, et al, DSS, pages 18-19)
Control Difficulty: Moderate.Sense Difficulty: Easy.This power may be kept up.Effect: This power works in a manner similar to that of the Lightsaber Combat power, but centers on defense. If a character successfully uses this power, he adds his Sense rating to his Melee Parry skill rolls while using a Sith Sword, and is able to add (but not subtract) part or all of his Control dice to the Sith Sword's damage. Additionally, blaster bolts can be deflected, and the system is the same as the one listed in SWD6, page 148.

Control and Alter Powers

Drain Energy (Adapted from DSS, pages 14-15)
Control Difficulty: Very Easy for simple devices (datapads, holorecorders, droid callers), Easy for power packs (blasters), Moderate for energy cells (lightsabers, force pikes, vibro weapons) and Difficult for portable generators (E-Web repeating blasters, droids).Alter Difficulty: Easy if the target is a non-sentient piece of equipment. If the target is a droid, the Alter difficulty is the droid's Strength roll.Required Powers: Absorb/Dissipate Energy.Warning: A character who uses this power automatically receives a Dark Side Point.
Effect: Use of this power allows a Jedi to drain the energy from power packs, energy cells, and similar power sources. This can render powered and electric equipment useless until the power source is replaced or recharged. Power generators larger than a portable generator, such as a fusion generator (used in power droids, vehicles, and ships) are too large to be drained by this ability. Using this power takes a full round. It can effect a single target within the character's line of sight up to 10 meters away. Due to the fact that this power uses Dark Side energy to siphon power, it grants the user a Dark Side Point.

Hatred (Adapted from DSS, page 18)
Control Difficulty: Moderate.Alter Difficulty: Target's Control or Perception roll.Required Powers: Control Pain, Inflict Pain, Injure/Kill, Life Detection, Life Sense, Rage, Waves of Darkness.Warning: A character who uses this power automatically receives a Dark Side Point.
Effect: This power is similar to "Force Scream" (ToJC, page 65) but is used voluntarily. The character using this power releases his hatred into a blast of Force energy. Successful use of this power deals 3D damage to all targets within ten meters of the character, and gives each one a -1D penalty to all rolls for the remainder of the round. The effects of this power last a single round, though the duration can be increased by spending character points  for each character point spent, the duration is increased by one round. These points can be spent at any time before the power fades.

Control, Sense, and Alter Powers

Alchemy (Adapted from DSS, page 13)
Control Difficulty: Moderate.Sense Difficulty: Moderate.Alter Difficulty: Varies (see below).Required Powers: Accelerate Another's Healing, Control Another's Pain, Control Pain, Enhance Attribute, Enhance Another's Attribute, Feed on Dark Side, Hibernation Trance, Injure/Kill, Life Detection, Life Sense, Place Another in Hibernation Trance, Sense Force, Sith Sorcery, Transfer Force.Warning: A character who uses this power automatically receives a Dark Side Point.
Effect: Using ancient Sith equipment and arcane formulae, a character with this Force power can alter the molecular composition of living beings, creating Dark Side mutants. All changes made to a being with this power create horrific physical mutations. Altering multiple aspects requires multiple rolls, with each roll taking one minute and granting an additional Dark Side Point. To use this power successfully requires thousands of credits worth of alchemical equipment and raw materials (as well as a subject). Each alteration made inflicts 4D damage against the subject. This power can also be used to reshape inanimate matter.

Illusion (Adapted from DSS, pages 15-16)
Control Difficulty: Moderate, modified by proximity.Sense Difficulty: Moderate, modified by proximity.Alter Difficulty: Target's Control or Perception roll.Required Powers: Affect Mind, Dim Another's Senses, Life Detection, Life Sense, Projective Telepathy, Receptive Telepathy, Sense Force.
This power may be kept up.Effect: Characters with the power of Illusion can manifest images that seem completely real to those who perceive them. These illusions cannot cause physical harm, though they might cause others to make mistakes if they do not realize their true nature. The maximum range for an illusion is 10,000 meters from the user. Maintaining an illusion takes complete concentration.

- Equipment -

Alchemical Apparatus (DSS, page 65)Cost for the proper alchemical apparatus is listed in the text. Specialized alchemical apparatus lower the difficulties of any Alter skill rolls related to the Alchemy Force power by 5 points. More versatile equipment can be used on any species, but only grants a +2 pip bonus to Alter skills rolls relating to Alchemy.

Dark Armor (DSS, pages 60-61)Dark armor is typically created to meet the needs of the wearer, and two suits are seldom the same. Most suits of dark armor are alchemically treated during construction in order to achieve certain desired effects. Dark armor is never simply found, and should be rare and hard to procure. With the proper skills and powers, GMs might allow players to construct their own suits of dark armor.

Creating Dark ArmorCreating dark armor requires the Technical: Armor Repair skill, and in some cases, the Alchemy Force skill. The character creating the armor must choose a standard type of armor as a basis for his design. Once the armor has been created, additional features (as listed below) can be added to the suit.

*Cortosis weave damages lightsabers. When a lightsaber strikes and inflicts damage on anyone wearing dark armor with Cortosis weave, roll the lightsaber's body strength (typically 2D) versus the damage rolled against the target, and consult the rules for "Damaged Weapons" on SWD6, page 95. For rules on repairing damaged weapons, see SWD6, page 60.
**This represents the difficulty of the Alchemy power's Alter skill roll.
***In addition to the cost of the armor, these qualities require the sacrifice of dark side energy in the form of a Force Point. Multiple qualities cost additional Force Points. The Force Points are lost if the skill roll fails.

Examples of Dark ArmorListed below are three examples of dark armor given on page 61 of the Dark Side Sourcebook, converted for use in SWD6.
Model: Dark Combat Jump SuitType: Dark ArmorScale: CharacterCost: 16,500 credits & 1 Force PointAvailability: 4, XGame Notes: A heavily-padded jumpsuit that incorporates Cortosis weave, a material that deactivates any lightsaber that damages the wearer. Grants +1D+2 to Strength rolls made to resist physical and energy damage. This armor also grants its wearer +1D to Perception or Control rolls made to resist the use of Projective and Receptive Telepathy, and increases the difficulty of Life Detection and Life Sense used against the wearer by +3.

Model: Dark Padded Battle ArmorType: Dark ArmorScale: CharacterCost: 12,000 credits & 1 Force PointAvailability: 4, XGame Notes: This armor provides the wearer with +2D to Strength rolls made to resist physical and energy damage. The armor is also imbued with Dark Side energy, granting the wearer a +1D bonus on rolls made to resist light side Force powers, or any Force power augmented by a light side Force Point.

Model: Dark Heavy Battle ArmorType: Dark ArmorScale: CharacterCost: 37,000 credits & 2 Force PointsAvailability: 4, XGame Notes: This heavily-plated armor conveys +3D to Strength rolls made to resist physical and energy damage. It is imbued with Dark Side stealth to keep the wearer hidden (+1D bonus to Perception or Control rolls made to resist the use of Projective and Receptive Telepathy, and increases the difficulty of Life Detection and Life Sense against the wearer by +3) and increased Strength (+2 pips to the wearer's Strength when making skill or attribute rolls, or when rolling melee damage).

Model: Massassi Chest Shield (see the text of the "Massassi" entry, DSS, page 114)Type: Alchemically-Treated Body ArmorScale: CharacterCost: Not available for saleAvailability: 4, XGame Notes: This is a Massassi warrior's primary body armor. It consists of an alchemically-treated shield strapped to the warrior's chest which allows increased freedom of movement. It provides +1D+1 to Strength rolls made to resist physical and energy damage to the chest only, and reduces the wearer's Dexterity by -1 pip.

Lanvarok, Massassi (DSS, page 58)
Model: Lanvarok, MassassiType: Disk launcher/PolearmScale: CharacterSkill: Thrown Weapons: Massassi Lanvarok/Melee Weapons: Massassi LanvarokAmmo: Enough for one burstCost: 250 creditsAvailability: 4, XRange: 2-5/10/20Difficulty: ModerateDamage: 3D+1/Strength +1D+2 (Max: 7D)Game Notes: Useable either as a ranged or melee weapon. When used as a ranged weapon, the disks launched from the lanvarok spread out, increasing the chances of a hit. This grants a 1D bonus to hit any target within 10 meters. Anyone using a lanvarok who also possesses the Telekinesis Force power can extend this bonus to the full range of the weapon with a successful use of that power. A lanvarok takes a full round to load.

Lanvarok, Sith (DSS, page 58)

The disks launched from the lanvarok spread out, increasing the chances of a hit. This grants a 1D bonus to hit any target within 10 meters. Anyone using a lanvarok who also possesses the Telekinesis Force power can extend this bonus to the full range of the weapon with a successful use of that power. A lanvarok takes a full round to load.

Lightsaber, Double-Bladed (DSS, pages 58-59;SWd20, page 117)
Model: Double-Bladed LightsaberType: Lightsaber: Double-Bladed LightsaberScale: CharacterCost: Not available for saleAvailability: 4, XDifficulty: DifficultDamage: 5DGame Notes: Proper use of a double-bladed lightsaber requires the specialization "Lightsaber: Double-Bladed Lightsaber." Without the proper specialization, the difficulty to use a double-bladed lightsaber is one grade higher than normal (ie, Very Difficult), and none of the special benefits of the double-bladed lightsaber may be used. If used with only a single blade projected, a double-bladed lightsaber is treated as if it were a normal lightsaber. If properly trained, a Jedi wielding a double-bladed lightsaber gains a +5 bonus to all parry rolls made when both lightsaber blades are extended.

Sith Poison (DSS, page 65)Sith poison can be either ingested, or introduced through an injury (wound, injection, dart, etc.). Any character so poisoned must succeed at a Very Difficult Strength roll or suffer 2D of damage. Additionally, the poison feeds the character's anger until it has been driven from his system. Whenever the afflicted character attempts to spend a Force point, he must make a Very Difficult Willpower or Control roll. Failure indicates that the character is overpowered by his anger and calls upon the Dark Side instead  thus gaining a Dark Side Point.
To overcome the poison, a character must make a total of five successful Willpower and/or Control rolls to resist the effects of the poison when spending Force Points. The character can use the Detoxify Poison Force power (Control Difficulty: Difficult) in addition to his normal Willpower or Control roll when resisting effects of the poison, and use the better of the two rolls to determine his level of success. Obviously, this can take some time.
Sith poison in rare, and can only be created with the Alchemy Force power (Alter Difficulty: Heroic). For every 5 points that the Alter difficulty number is exceeded, an additional dose is created. No matter how many doses are made, the person making the poison must spend a Force Point and gains a Dark Side Point.

- Artifacts -

Orbalisk Armor (DSS, pages 67-68)Orbalisk infestation has much the same effect in D6 as listed in the DSS text on pages 67-68 (insofar as the number of orbalisks required to cover a host, and the physical effect thereof). The biochemical reaction created by the mixture of Dark Side energy and orbalisk venom can be reflected in a Strength increase of +1 pips for every 20% of coverage. Additionally, characters who are host to orbalisks can make natural healing rolls twice as often for every 20% of coverage (see below).

Sith Amulet (DSS, pages 66-67)
Model: Sith AmuletType: Ancient Sith RelicScale: CharacterSkill: AlterAmmo: UnlimitedCost: Not available for saleAvailability: 4, XRange: 1-5/10/20Damage: 6DGame Notes: Sith amulets are typically built in the form of crystal-studded gauntlets. When used by a character who has the Alter Force skill, the amulets project focused blasts of Dark Side energy similar to those created by the "Bolt of Hatred" Sith power (ToJC, page 87). The user's skill roll equals his Alter skill code, and the attack can be dodged like any other ranged attack. Each time a Sith amulet is used, the user gains a Dark Side Point.

Darth Maul's Sith speeder was equipped with a "safe release" system. If the handlebars of the speeder were released for any reason, the speeder would automatically slow its speed by half each round until the handlebars were gripped again.

Poison Dart Needler: This needler gun is loaded with darts that contain a paralytic poison. The darts inflict no damage, but if used against an unarmored target (or an unarmored portion of a target, see the rules for called shots, SWD6, page 91), they inject their poison. The target of such an attack must succeed at a Difficult Strength check or be paralyzed and unable to move for 1D x 40 minutes (40-240 minutes). No ammunition total is listed, so assume the needler gun carries enough darts for ten shots.Move: 10Size: TinyCost: Not available for sale.

If successfully removed in this manner, an orbalisk inflicts 1D+1 damage to its former host.Poison: An orbalisk injects venom into its host. When injected into characters with Dark Side Points, this venom has certain properties. Characters who are host to one or more orbalisks must succeed in a Difficult Strength check each day or take 1D+2 poison damage per orbalisk (meaning that anyone host to five orbalisks will take 8D+1 poison damage without a successful roll). Characters with Dark Side Points get a +1 pip bonus to this Strength roll for every 2 Dark Side Points they have, and characters with more then 36 Dark Side Points do not have to roll at all.

- Miscellaneous Rules -

Dark Spirits (DSS, pages 122-125)Dark Side spirits work the same as most characters, retaining most of the abilities and attributes it had when it was alive. Any attack that deals physical damage will not harm a Dark Side spirit, nor can a Dark Side spirit make direct physical attacks against living characters. Any Force powers with physical effects (ie, Alchemy, Telekinetic Kill, Injure/Kill, Accelerate Healing in Another, Telekinesis, Force Lightning, etc.) are ineffective when used by or against a Dark Side spirit . Any damage caused by these powers is reduced to zero. Dark Side spirits receive a +3D bonus on all Hide, Sneak, and Search rolls that they make.

Dark Side spirits have the following abilities in addition to those they had in life:

ManifestationBeing nonphysical, Dark Side spirits are not affected, nor can they affect, anything physical. When they do manifest, they can be seen and heard. In order to remain audible and visible, a Dark Side spirit must succeed in an Easy Strength roll once per minute. Failure indicates that the spirit's voice and likeness fade until it manifests again.

PossessionBy using the power of Sith Sorcery, a character opens himself up to potential possession by Dark Side spirits (see the "Sith Sorcery" Force power). Dark Side spirits can also attempt to possess other physical bodies, but such an attempt grants the potential victim an Easy Willpower roll to resist. If a Dark Side spirit attempts to possess someone unsuccessfully, it may not try to possess that character ever again.
Once a Dark Side spirit has possessed a body, it retains its own Knowledge, Pereption, and Technical attributes in addition to its own skills, and uses the Dexterity, Mechanical, and Strength attributes, as well as any physical abilities, of its host. The Dark Side spirit can exit the body at any time. If the body is killed while possessed by the Dark Side spirit, the spirit is forced out but otherwise remains unharmed.
While a Dark Side spirit occupies a body, the body's original occupant is forced out and becomes, for all intents and purposes, and Dark Side spirit. It may attempt to repossess its former body, or can try to possess a different one.

Force TravelDark Side spirits can use the Force to instantaneously travel to any point in the galaxy, though there must be some form of Dark Side energy there to act as a sort of "beacon." The spirit must be familiar with the destination. To use this ability, the spirit must succeed at a Willpower roll, with the difficulty based on the distance traveled.

Below, you will find book and page references to everything in the "Dark Side Sourcebook" that has been previously detailed in WEG products. If it's on this list, that's why I haven't presented conversion information for it. This list might also be useful for players and GMs of SWd20 who are looking for additional reference material on any of the following subjects. Be warned, I only plan to list up to three or four references for each entry.
